The SCHNEIDER ELECTRIC LA1KN04 is an auxiliary contact block designed to expand the contact capacity of compatible contactors in industrial and commercial electrical control systems. This accessory mounts directly to the contactor body and adds normally open or normally closed contact circuits for control, signaling, or interlocking functions. Weighing just 0.09 pounds, it is a compact unit measuring 1.4 inches in length, 1.3 inches in width, and 1.6 inches in height. Licensed electricians and industrial maintenance technicians are the primary installers of this component in motor control and panel wiring applications.
The LA1KN04 auxiliary contact block is intended for use with CA2K, CA3K, and TeSys K series contactors. These contactors are commonly found in motor starters, control panels, and automation assemblies in light industrial and commercial facilities. The block clips onto the front or side of the base contactor to extend control circuit capability without requiring additional panel space or separate relay hardware. It is suited for both new panel builds and field retrofits on existing TeSys K installations.
Designed for use with Schneider Electric CA2K, CA3K, and TeSys K series contactors as stated by the manufacturer.
Installation should be performed by a qualified electrician in accordance with NEC requirements and local electrical codes. De-energize and lock out the panel before attaching or removing the auxiliary contact block. The block snaps onto the contactor body — verify seating and mechanical engagement before re-energizing. Do not exceed the contact rating of the base contactor assembly when adding auxiliary circuits.
